AMIN: Difference between revisions

Latest revision as of 14:07, 8 April 2022

AMIN = [real]
Default: AMIN = min(0.1,AMIX,AMIX_MAG)

Description: AMIN specifies the minimal mixing parameter in Kerker's initial approximation^[1] to the charge-dielectric function used in the Broyden^[2]^[3]/Pulay^[4] mixing scheme (IMIX=4, INIMIX=1).

Kerker's initial approximation^[1] for the charge-dielectric function is given by

A\times \min \left({\frac {G^{2}}{G^{2}+B^{2}}},A_{\rm {min}}\right),

where $A$ =AMIX, $B$ =BMIX, and $A_{\rm {min}}$ =AMIN.
